document.write('<div style="background-color: #fee; border: 2px dashed red; padding: 5px"><b>Important</b><br /><br /> Internet Explorer does not natively support the HTML5 canvas tag, so if you want to see the charts, you can either:<ul><li>Install <a href="http://code.google.com/chrome/chromeframe/">Google Chrome Frame</a></li><li>Use ExCanvas. This is provided in the OfficeExcel Archive.</li><li>Use another browser entirely. Your choices are Firefox 3.5+, Chrome 2+, Safari 4+ or Opera 10.5+. </li></ul> <b>Note:</b> Internet Explorer 9 fully supports the canvas tag.</div>');

The Gantt chart can be adjusted by dragging the bars left or right, or the events can be resized if you place the cursor at the
|
|
right edge of the event. To get the details of the bar being dragged you can use the
|
|
<i>onadjustend</i> event, and in that you can look at the OfficeExcel registry - <i>OfficeExcel.Registry.Get('chart.adjusting.gantt')</i> The
|
|
returned array consists of:
|
|
|
|
<ul>
|
|
<li>The numerical index of the event being adjusted (corresponding to the chart.events array that you set).</li>
|
|
<li>The chart object</li>
|
|
<li>The starting X position of the bar (before the chart was adjusted)</li>
|
|
<li>The starting Y position of the bar (before the chart was adjusted)</li>
|
|
<li>The original numerical value (in relation to your chart.xmax) that the bar started at</li>
|
|
</ul>
|
|
</p>
|
|
|
|
<p>
|
|
When adjusting is complete the <i>chart.events</i> array is updated. So you can use the numerical index that you find in
|
|
the registry (as above) with the <i>chart.events</i> array to get up-to-date event information.
|
|
</p>
|
|
|
|
<p>
|
|
<b>Note:</b>
|
|
The Gantt chart uses console.log() to send notifications. Press CTRL+SHIFT+J in Chrome to see the console, or use Firebug in
|
|
Firefox. Other browsers will vary.
